Figure 3-1. Unpacking the Cabinet

INSTALLATION SITE REQUIREMENTS

A stable, clean, and uncluttered area should be carefully considered when selecting an installation site. The equipment cabinets are designed to fit easily in the installation site. The cabinets are compact and operate quietly, so they can be placed in an office or work area.

Before the system can be installed, the operations in this chapter must have been completed.

Keep in mind the following environmental considerations in the selection of an installation site:

. The installation site should be clean, dry, and uncluttered to limit the intake of dust and dirt into the cabinet.

. The installation site should e well ventilated to dissipate warm air vented from the equipment cabinets.

. The installation site should be well lighted to make installation and maintenance easier.

. The installation site ambient temperature must be maintained between 32” and 104” Fahrenheit (0’ to 40” Celsius).

. The installation site should be maintained at a relative humidity between 10% and 90% (non-condensing) over the specified temperature range.

. The minimum wall load requirement for mounting a Series 3 cabinet is 55 pounds per cabinet.

. The equipment location should be subject to very little vibration

l There should be enough AC power outlets and circuits for the

system and its peripheral hardware.

. _{The equipment location should be free of overhead water pipes} which might rupture and damage the equipment.

l The equipment location should be free of strong magnetic fields,

such as those created by large transformers. Also, avoid an area where there is apt to be static electricity.

l The equipment location must be free of corrosive fumes or

machine exhaust which might cause deterioration of circuit components.

. _{The equipment location should not have heating ducts or} adjacent windows which could cause the ambient temperature to rise above or fall below the rated operating range.

. _{The equipment location must allow adequate air circulation} through the cabinet.

SPECIAL INSTALLATION l Never install telephone wiring during a lighting storm.

INSTRUCTIONS _.

Never install telephone jacks in wet locations unless the jack is designed for wet locations.

. _{Never touch bare telephone wires or terminals unless the} telephone has been disconnected at the network interface. . _{Use caution when installing or modifying telephone lines.}

HEAT LOADING

GROUNDING REQUIREMENTS

. _{Typical heat generated:}

- About 956 BTU (single cabinet/70 lines) - About 1853 BTU (two cabinet systeIl50 lines) - About 2809 BTU (three cabinet system/220 lines) - About 3703 BTU (four cabinet system)

Although standard power provides an acceptable level of performance for most installations, some will require the power failure transfer feature which switches designated stations to assigned outgoing trunks during power outages.

Some facilities (particularly those with computer installations) are equipped with an Uninterruptable Power Supply (UPS). This is the preferred power source since it provides automatic switchover to 120 VAC back up in case of a loss of power. If a UPS is available at the facility, the installer should verify that the Series 3 system power

outlet is connected to the UPS system.

Battery back up for the Series 3 is described in Chapter 8. . _{Signal ground: A single wire is connected to the G (center)}

terminal of the terminal block in the bottom of cabinet zero (Basic). Refer to Chapter 4. This wire must be 12 AWG, stranded or solid copper conductor. The resistance of the connection from the terminal block to the Utility Entrance

Ground must not be greater than 5 ohms.

GENERAL

WALL MOUNTING BRACKETS

Attaching the Mounting Bracket

Drilling the Mounting Bolt Holes

Wall Bracket Grounding

The following procedures detail the mounting of wall brackets, cabinets, and the connection of the inter-cabinet cables.

Each bracket will support one cabinet.

When planning the layout for a system with expansion cabinets located above or below the basic cabinet allow a minimum 12 inches between the top and bottom mounting brackets. The space is required for MDF cable clearance and cooling air flow. The

maximum spacing is 24 inches. Refer to Chapter Two.

Each mounting bracket has four sets of bolt holes. Refer to Figure 4-l. Bolt Hole Set One is used to attach the bracket for the first cabinet in a row. Bolt Hole Set Two is used to attach the second cabinet bracket. The basic cabinet (cabinet zero) is always the first cabinet; expansion cabinet one mounts to the right of the basic cabinet. Attach the mounting bracket to the wall using either expansion bolts, or bolts and insert sleeves. The bolts must be at least 114 in. diameter; or, if mounting the bracket on wood, the minimum size wood screw permitted is a 114 x 5/8 inch. The method used to secure the bracket must be capable of supporting 55 pounds (25 kg).

Drill the bolt holes as follows:

1. Find and mark the stud locations behind the walls where the bracket is to be mounted. The mounting bracket provides holes for 16-inch center-to-center stud distance.

2. Mark the positions of the four holes to be drilled in the wall for the mounting bracket. For the basic cabinet use Bolt Hole Set

One.

3. Mark the center of the holes using a drill or punch.

4. Drill each marked hole to the correct depth and width for the bolts/sleeves or screws to be used.

5. If sleeve inserts are used, drive one into each of the holes. 6. If another bracket is to be installed to the right; attach the FIRST

bracket to the wall. Set the right bracket in place, next to the left bracket. Notice that two right side tabs fit under the main plate of the left mounting bracket. Align the Set Two holes in the new

bracket tabs with the Set One hole in the right side of the first bracket. Ensure that the left bracket frame ground tab is over the hole in the right bracket. Mark the wall through the Bolt Hole Set Two holes.
